Kelly Clarkson Just Covered Your Favorite '00s Anthem

The former American Idol winner treated fans to yet another cover song. This time she busted out the 2000 TRL favorite "Bye Bye Bye," a.k.a. the *NSYNC hit you still can't hear without seeing Justin Timberlake and Joey Fatone dangling like marionettes.

"Tonight is fun," Clarkson told the crowd. "This is a throwback to our junior high days. And a lot of people in our crew are very excited about this one.”

Who wouldn't be? Not surprisingly, Clarkson once again took a fan request and crushed it. Can't wait to see what she pulls out next.
